APPARATUS FOR SAMPLING STREAMS OF 'WET CRES AND THE LIKE.

Application filed December 1, 1915.

To all whom t may concern:

Be it known that I, CHARLES JOHN WIL- LIAMS, a subject of the King of Great Britain, residing at The Bungalow, Carnon Valley, Perranwell, in the county of Cornwall, England, haveV invented new and useful Apparatus for Sampling Streams of TNet Orcs and the like, oic which the' following is a specification.

This invention relates to apparatus for automatically taking samples of wet ores, or other similar materials.

Referring to the accompanying' sheet of explanatory drawings Figure 1 isa sectional front elevation of the apparatus.

Fig: 24 is an end elevation with the scoop broken off to show the stop pieces, and

Fig; 3 is a plan with the rear end of the tank broken o6 to show the position' of the scoop when taking' a sample.

The same reference numerals indicate corresponding parts throughout the figures.

The invention is shown asv applied to the sampling of wet ores which are being conveyed along a launder 1, tol which the apparatus is attached in any convenient position of its length.

The apparatus comprises a scoop 2 and arms 3 which are attached to the spindle 4 supported at each end by the pivot pins 5. A water tank 6 isv iiXed to the arms 3 and is fitted with a sliding cover 7, and a locking screw 8 for securing said cover in the position to which it has been adjusted. A hole 9 is provided in the cover 7 for the admission of water to the tank 6 from the water supplyA 10 suitably arranged above said opening. A counter balance lever 11 is attached to the spindle 4, the balance weight 12 thereofbeing adjustable to any position along said lever. A stop pin 13 forms a rest for supporting the balance lever 11 in its lowermost position. The purpose of the adjustable weight 12 is to counterbalance the weight ofthe scoop 2, and the water tank 6 (with its contents).

The apparatus above described is mounted on a stepped launder 1 along which the ore is to be conveyed. A connecting boX 14 unites the two sections at the junction of the upper section 1fl with the lower section 1b, such connecting box being composed of sides 15, and bottoms 16 and 17 constituting the means oi attachment to said launder. A discharge or sample chamber 18 is formed in- Specicaton of Letters Patent.

Serial No. 64,548.

termediatel to the bottoms 16 and 17 of the connecting box 14, and at 19 is provided with means for attachment of a pipe to carry off thel sample discharged into chamber 18 as hereinafter described. A splash plate or riser 20 serves to prevent wet ore splashing, or trickling back into the chamber 18.

The operation of the appara-tus is as follows Vlren the apparatus is in the position shown in F ig. water flowing from the tap 10 passes through hole 9 in cover 8 and enters tank 6', and when the weight of water therein is suiiicient toV overcome thel resistance due tothe balance weight 13, said tank 6 and the scoop 2' tip over radially, the latter cutting the stream of ores at right angles to the direction of flow until it is arrested by contact withA the stop pieces 21.

the lannder without interruption until theY operation of the apparatus is repeated by the refilling of the tank 6 by the water issuing from the tap 10.

To control the length of time that the scoop 2 remains in its operative position, c'. c. when in the position shown. by broken lines in Fig. 1,V the cover 7 with which the water tank 6 is provided is made adjustable so as to regulate the size of the discharge opening 22, and thus control the time required or the water tank to empty itself, whereby the scoop Q will remain in position for diverting the wet ore from the launder 1 into chamber 1S or the connecting box 14, for a longer or shorter period as may be required.

The adjustment of tap -10 of the water supply by regulating the time required for iilling the tank 6 to the required extent to overcome the weight of the balancing lever ll, will determine the periods at which the tipping of the apparatus will occur, and consequently at which the samples areA intermittently taken from they ore passing along the `launder 1, by the scoop 2V temlao porarly diverting the flow thereof into the chamber 18, whence it will be conveyed by a conduit attached. to the discharge oriice 19.

vWhat I claim as my invention, and desire to secure by Letters Patent, is

l. An ore sampling apparatus comprising a channel having stepped sections for the iiow of material to be sampled, a sample chamber disposed underneath the delivery end of a section of said channel and having a receiving opening below said channel end, a pivoted scoop adapted to connect said channel end with said chamber opening,'said scoop being fulcrumed transversely of said channel and adapted to swing downward through the flowing stream to be sampled, a counterbalance for said scoop, and means for periodically swinging said scoop downward into operative position.

2. An ore sampling apparatus comprising a channel having stepped sections for the low of material to be sampled, a sample chamber disposed underneath the delivery end of a section of said channel and having a receiving opening below said channel end, a pivoted scoop adapted to connect said channel end with said chamber opening, said scoop being fulcrumed transversely of said channel and adapted to swing downward through the flowing stream to be sampled, a counterbalance for said scoop, and a tank mounted on said scoop and provided with means 'or receiving a liquid when the scoop is in upward inoperative position for depressing it into operative position and with means for discharging said liquid when the scoop is in downward operative position to permit the rising thereof under the action of the counterbalance.

3. An ore sampling apparatus comprising a channel having stepped sections for the flow of material to be sampled, brackets disposed on opposite sides of said channel, a horizontal spindle supported in said brackets above said channel transversely thereof, a sample chamber disposed underneath the delivery end of a section of said channel and having a receiving opening below said channel end, a scoop attached to said spindle and adapted to connect said channel end with said chamber and provided with upwardly extending arms at an angle to said scoop, a counterbalancing device connected with said scoop, and a tank attached to said arms above said scoop and provided in its upper part with an opening for receiving a liquid for depressing said scoop into operative position and in the end which when tilted becomes its lower part with means for discharging said liquid when the scoop is in downward operative position to permit the rising thereof under the action of the counterbalance.

Ll. An ore sampling apparatus comprising a launder having stepped sections and a riser between the delivery end of the upper section and the receiving end of the lower section, said riser having an opening, a sample chamber disposed underneath the delivery end of said upper section and behind said riser, a pivoted scoop ulcrumed transversely of said launder at the delivery end of said upper section thereof and adapted to swing downward through the flowing stream to be sampled into operative relation with said opening, forming a connecting conduit between said upper section and said sample chamber operative to direct the How of material from 'said launder into said chamber, a counterbalance for said scoop, and means for periodically swinging said scoop downward into operative position.

5. An ore sampling apparatus comprising a launder having stepped sections and a riser between the delivery end of the upper section and the receiving end of the lower section, said riser having an opening, a sample chamber disposed underneath the delivery end of said upper section and behind said riser, a horizontal spindle disposed transversely of said launder at the delivery end of said upper section thereof, a scoop fixed to said spindle, upright arms in fixed relation to said spindle, a water tank supported on said arms and having an upper inlet opening adapted to receive water for depressing said scoop into operative position and with lower discharge means operative for releasing said scoop when tilted into inoperative position, a counterbalance arm attached to said spindle and carrying an adjustable balance weight, and means for supplying water to said tank, said scoop being adapted to cut the stream flowing over said upper section and to close into operative relation with said opening, forming a connecting conduit between said upper section and said sample chamber and serving to direct the flow of material from said launder into said chamber.

6. An ore sampling apparatus comprising a launder having stepped sections and a riser between the delivery end of the upper section and the receiving end of the lower section, said riser `having an opening, a sample chamber disposed underneath the delivery end of said upper section and behind said riser, a horizontal spindle disposed transversely of said launder at the delivery end of said upper section thereof, a scoop lixed to said spindle, upright arms in fixed relation to said spindle, a water tank supported on said arms and having an upper inlet opening adapted to receive water for depressing said scoop into operative position and with lower discharge means operative for releasing said scoop when and said sample chamber and serving to direct the iiovv of material from said launder into said chamber.
